Efficient dust-absorption multistage coal mine stone crushing device

Abstract

The invention relates to an efficient dust-absorption multistage coal mine stone crushing device, and belongs to the technical field of coal mine stone crushing equipment. The efficient dust-absorption multistage coal mine stone crushing device comprises a box body, a first-stage crushing chamber, a second-stage crushing chamber and a dust removal chamber; the first-stage crushing chamber and thedust removal chamber are arranged at the upper part in the box body, the second-stage crushing chamber is arranged at the lower part in the box body, and a coal mine stone inlet is formed in the upperpart of the box body; the coal mine stone inlet is in communication with the first-stage crushing chamber, an outlet of the first-stage crushing chamber is in communication with an inlet of the second-stage crushing chamber, so that the preliminarily crushed coal mine stone enters the second-stage crushing chamber; and an opening is formed in the lower part of the side wall of the second-stage crushing chamber, the opening is in communication with a discharge port of the box body, and the crushed finished coal mine stone is discharged. According to the efficient dust-absorption multistage coal mine stone crushing device, the crushing speed fast, the efficiency is high, dust can be absorbed in the crushing process, so that pollution is prevented, the multistage crushing of the coal mine stone is realized, meanwhile, an air curtain is used for collecting the dust, finally a filter screen is combined to remove the dust, and the crushing and the dust removal efficiency are high.

Description

technical field [0001] The invention relates to the technical field of coal ore crushing equipment, in particular to an efficient dust-absorbing multi-stage coal ore crushing device. Background technique [0002] In mine production, the raw coal initially mined has a large block, which is not conducive to the transportation of ore. Generally, a coal ore crushing device is installed inside the mine to crush the larger raw coal before transportation. The current coal ore crushing device is easy to cause damage to the crushing chamber due to the large coal ore block during operation, and the crushing efficiency is not high during crushing, and there will be a small amount of raw coal with large blocks that cannot be crushed up to the standard. [0003] Therefore, in recent years, factories have higher and higher requirements for coal, and more and more customers no longer need directly mined coal, but coal powder or small-sized coal ore, but when crushing raw coal A large amo...

The current coal ore crushing device is easy to cause damage to the crushing chamber due to the large coal ore block during operation, and the crushing efficiency is not high during crushing, and some raw coal with large blocks will not be crushed up to the standard

[0003] Therefore, in recent years, factories have higher and higher requirements for coal, and more and more customers no longer need directly mined coal, but coal powder or small-sized coal ore, but when crushing raw coal A large amount of dust will be generated, which will not only pollute the air environment, but also cause certain harm to the health of operators. At the same time, most of the crushing equipment will be incompletely crushed, resulting in a certain amount of waste.

The dust removal mechanism in the existing multi-stage crushing device is generally a wet dust removal that sprays water to the crushing chamber, which is likely to cause blockage of the dust removal mechanism, reduce the crushing rate of coal ore, and generate a large amount of waste water. It is also necessary to set up a special sedimentation treatment mechanism for waste water
